[Bleeding] Correct issues with MEGA_REDWOOD trees. Fixes BUKKIT-5568

In commit 6efeddfe57, TALL_REDWOOD was used instead of the proper TreeType
of MEGA_REDWOOD. Additionally, this fixes an issue in CraftWorld with an
improper boolean flag related to the generation of MEGA_REDWOOD trees.
[Bleeding] Allow generation of cocoa trees.
[Bleeding] Include equipment in EntityDeathEvent loot. Fixes BUKKIT-5566
[Bleeding] Recheck persistence for chicken jockeys each tick. Fixes BUKKIT-5577
Implement inventory creation by type and title. Fixes BUKKIT-4045

With the current API it is possible to create an inventory with a specific
type, but it is not possible to give such an inventory a title other than
the default.

The commit changes that by adding a method to optionally supply the title
for the given inventory type and holder, creating the functionality to
display any supported inventory type with a 32 character length String.

If the inventory title supplied is larger than 32 characters then an
IllegalArgumentException is thrown stating so.
